The red-band trailer kicks off with Rogen and James Franco -- as themselves -- taping a grainy video message on 12/21/2012, the day the Mayans declared would be the day the world ended. "F---ing Mayans!" (Plus, the two sword fight, get high and share a bed because hey, what else is there to do while you wait for the end of the world to hit?)

The star-studded cast includes Rogen, Franco, Jay Baruchel, Danny McBride, Jonah Hill and Craig Robinson trying to make sense of what happened to their friends Michael Cera, David Krumholtz and Jason Segel. "Guess if Michael Cera's dead, it's not a total loss right?" McBride ponders aloud before laughing. "Michael Cera's dead!"

Sound of glass breaking interrupts the group's conversation and when they realize what it is that appears before them, the natural response would be to scream ... like a girl, as Robinson does. A montage of scenes from This Is the End, including a box crashing onto a register lady, laser beams in a cubicle-filled office, craters and a blink-and-you'll-miss-it cameo by Emma Watson, followed with a bonus line from Robinson about just how far he goes to survive the post-apocalypse.
